Schwannoma

The scans show an intradural extramedullary lesion centred in the left C6/7 foramen. The cord is compressed and displaced, and there is complete effacement of the CSF. There is abnormal signal within the cord which may represent myelomalacia. The lesion appears dumbbell-shaped, and my first differential would be a nerve sheath tumour. Other differential diagnoses include meningioma and neurofibroma.

Progressive spondylitic pathology can lead to central spinal canal stenosis and the development of a myelopathy (see Revision panel 9.1) as the spinal cord is compressed. This can be either dynamic, when cord compression occurs only on movement, or there may be instability of the cervical spinal column, causing compression of and damage to the spinal cord, termed myelomalacia. There may not be neck pain, but stiffness is a common feature.

About 17 (74%) out of 23 patients with a spinal deformity or canal compromise showed spinal cord changes on the MRI. While only 8 (23%) of the 35 patients without spinal deformity or canal compromise showed spinal cord changes (p ≤ .05). Secondary spinal cord changes and its distribution among the two groups are summarized in Table 1. Spinal cord atrophy was found in seven patients with a spinal deformity or canal compromise and three patients without spinal deformity (p ≤ .05). Similarly, the occurrence focal cyst was significantly higher in spinal deformity patients group (p ≤ .05). The occurrence of myelomalacia and syringomyelia was more frequent in patients with spinal deformity and or spinal canal compromise.
Centrally mediated obstructive apnoea and restenosis of the foramen magnum in an infant with achondroplasia

We report an infant with achondroplasia in whom the main manifestation of foramen magnum stenosis was obstructive sleep apnoea. There was no change in neurological status to indicate progressive narrowing, although intracranial imaging showed the development of myelomalacia at the level of the CMJ. Initial foramen magnum decompression was bone only but the patient had a minor short-lived improvement. Bone re-formed over the intact dura and a second more extensive operation was done followed by a significant resolution of the respiratory symptoms.
